'Chuck': Man-crush alert! Joshua Grimes and Isaiah Mustafa

"Chuck" returns Monday (March 14) after taking last week off, and it brings with it a pair of returning guest stars in
Isaiah Mustafa and
Stacy Keibler.

Yes, we're finally going to find out a little bit about the "Greta" program from earlier in the season --
it wasn't just stunt casting after all. And, from the looks of the video above, Monday's episode, "Chuck vs. the A-Team," also allowed
Joshua Gomez to rekindle his man-crush on Old Spice pitchman Mustafa.

Sample questions, which Gomez claims to have culled from Twitter: What's it like being so excellent -- is that really exciting? Do you spend time with other highly excellent men? Do you have any other powers besides superhuman levels of excellence? (You get the idea.)

It's not a one-way street, though: Mustafa also has great admiration for Gomez ... or at least for his beard. And now we're really hoping for a scene or two of Gomez and Mustafa interacting in the episode, because that was a fun two minutes.

As for an actual, plot-related preview? There's a quick one below, in which Mustafa is considerably less cheery. "Chuck" airs at 8 p.m. ET Monday on NBC.
